Specific embodiment

Describe for network-accessible discovery service center realize intelligence configuration discovery technique method and apparatus, For providing the visualization technique for automatically updating view of configuration information and the migration market of the client for assisting discovery to service The various embodiments of the migration promoter of service and the decision for making the migration about application program.In high level On, configuration discovery service can be realized based on following item (such as constitutes application program to configuration item (in addition to other features) Physics or virtualization calculation server, storage device, database, stack components etc.) and distributed application program mode oneself Dynamic detection: by the initial data of multiple data sources collection, the appointment of unique identifier to configuration item, to the interaction items The tracking of (for example, affairs, network flow etc.) and dependence, application program configure variation over time and are directed to multiple Performance monitoring under the required granularity level of miscellaneous application execution environment.Configuration discovery service is alternatively referred to as in some environments Application program discovery service or resource discovery service, because configuration item is the component to form application program.Configuration discovery service can Realize a variety of programming interface (for example, web services application programming interfaces, command line interface etc.), the interface is for services client End use obtain to configuration relevant inquiring response, and also act as other service (including migration market service and visually Change service) building block to provide the function of higher level.In some embodiments, be attached to configuration discovery service or its The Visualization Service of a part may act as one of the main interactive mode of client of configuration discovery service, for example, client may Enough check its be suitable for used in the customization of application execution environment of particular customer end side display environment indicate, by can Configuration relevant inquiring, and/or starting are issued from one group of resource to the partial or complete application program of another group of resource depending on changing interface Migration.In various embodiments, migration market may act as intermediary service, and the intermediary service enables a client to mark and closes Suitable migration promoter, and migration promoter is made to can be identified for that candidate client, for example, application program is stayed from client Ground is moved to calculating environment based on cloud or is moved to another from an environment based on cloud.

In at least some embodiments, some or all of service can be realized at provider network.By such as public The entities such as department or public sector's tissue are established to provide and be visited for one group of distributed clients by internet and/or other networks The network for the one or more Network Accessible Services (such as various types of calculating services based on cloud or storage service) asked It can be described as provider network herein.Provider network can be described as " public cloud " environment sometimes.The resource of provider network exists It can be distributed in multiple data centers in some cases, the data center can then be distributed in many cities, state and country In.Although should be noted that configuration discovery service, Visualization Service and/or migration market service can be in specific provider networks It realizes, but some or all of these services can be authorized to the information from other provider networks and visit is awarded Ask the appropriate power of the information from other provider networks (for example, the provider network for carrying out freely different establishment's operations) Limit.For example, the configuration discovery service run at the provider network PN1 of operator O1 operation can be acquired from operator O2 Operation provider network PN2 (and the data center of the data center and PN1 oneself possessed from such as client other Facility) configuration data collected, the Visualization Service run PN1 at aloows client to check to be included at PN2 fortune The distributed application program framework of capable component, and/or the migration market service run at PN1 can be to client The information about migration promoter is provided with the assembly transfer for will run at PN2 to PN1.In some embodiments, Visualization Service and/or migration market service can realize the sub-component for configuration discovery service.Configuration discovery service is herein It can be also simply referred to as discovery service.

The repository of configuration record can be constructed using various data sources in configuration discovery service center.For example, In some embodiments, data source may include that the existing configuration management database at client data center (can pass through volume sometimes Journey interface bulk import configuration data), in order to various resources configuration discovery service installation agency or configuration data collector, Third party or professional standard configuration management tool etc..Each data source can service at one or more time points to configuration discovery There is provided configuration information, it may for example comprise the attribute-value pair of some quantity of configuration item is organized with Mr. Yu.In at least some embodiments In, some data sources can provide original configuration data at regular intervals, and others can be it is event driven.In various realities It applies in scheme, is worth targeted configuration item attribute except other in service center (for example, passing through the agency in order to service installation) acquisition Except item, it may include user information (such as user's name and master catalogue), group information (such as group name and group membership), The list of software package/program and the list of kernel module have been installed.In at least some embodiments, also collect about perhaps The information of mostly different types of configuration dependent event, such as process creation/termination (associated Process identifier), domain name Service (DNS) is inquired and response, the data packet at each layer of network stack send and receive etc..Physics and/or virtual net Value (the maximum of type (Ethernet such as currently in use), support including such as network interconnection of each attribute of network interface Bandwidth, associated media access control or MAC Address etc.) it can collect to obtain from the device of target execution environment.It can identify The specific network ports that various Energy Resources Service use, such as TCP (transmission control protocol) or UDP (User Datagram Protocol) port, And 6 connection attribute of TCP edition 4 or version is collected (when the identifier of the process at either end such as connected, connection are established Between, duration for keeping it turning on of connection etc.).In some embodiments, operating system association attributes are collected, including for example The specific version of the operating system used in various hosts and virtual machine.It in different implementation scenarios can various intervals receipts Collecting system performance and process performance measurement.In some embodiments, it is found that multiple agencies of service are mountable in given host Or at device, to collect the respective subset of the configuration attribute value of one or more configuration items；In other embodiments, single generation Reason or tool can extract attribute value from several different sources.

Configuration discovery service may act as receiving under corresponding granularity level and according to corresponding timetable from various data sources The possibility of collection is out-of-date, conflict and/or ambiguous original configuration information combiner and planner.According to different numbers According to source, in some embodiments, configuration discovery service can be responsible for generating and storing the configuration record of merging and planning；Such conjunction And record may act as Visualization Service and migrate market service (or dependent on discovery service other service) configuration data Authoritative source.In at least some embodiments, configuration discovery service can be based at least partially on the ontology by service definition Unique device side identifier is generated and assigned to each configuration item.For example, given hardware server can be by a data source One of IP address (can change over time) based on server is based on server name or MAC (matchmaker by another data source Body access control) address, by third data source be based on server in distributed application program institute's role (for example, " web server " or " database server ") etc. identify.In the original configuration data for being supplied to configuration discovery service, Data source can respectively include the corresponding server identifier/title of themselves.This class identifier can be described as counting herein According to source identifier.Configuration finds that service can be checked from the received original configuration data of one or more of different data sources, And it is raw to server based on defined ontology and nomenclature scheme (subset of the attribute value of initial data may be taken into account) At unique device side identifier.

Unique device side identifier can be different from least some of the identifier/name that is used by data source.At least In some embodiments, when service center receives or analyzes one group of new original configuration data, service can determine to Unique identification configuration item applied by few a part of initial data, although unique identifier is not present in initial data.One In a little embodiments, service can be responsible for the mapping between the identifier and unique device side identifier that maintain data source to provide, with And for solving ambiguity associated with such mapping (for example, changing the feelings of the identifier of its given configuration item in data source The ambiguity being likely to occur under condition).Number of mechanisms can be used to solve ambiguity in different implementation scenarios, for example, being based on About within some periods from the original configuration data of other data sources association analysis, based on client feedback etc. Deng.In a kind of example scenario, for example, two different unique device side identifiers initially (mistakenly) may be assigned to phase With configuration item (such as based on from two different data sources received corresponding original configuration data set DS1 and DS2), as a result, Two different merging configuration record R1 and R2 and corresponding different service side identifiers are storable in service repository.Slightly Afterwards, for example, after the one or more other raw data sets of processing and/or in the interaction for passing through programming interface and client Later, it can detect and correct mistake.That is, service can determine that the attribute for the value being stored in R2 is actually corresponding with R1 Configurations item attribute.For example, this determination can be made based on the analysis of resource consumption information.If initially mistakenly Assuming that two configuration items associated with R1 and R2 are different hardware server, but discovery is two related whithin a period of time Cpu busy percentage is horizontal or the collected measurement of network packet outflow is closely similar or identical, then record R1 and R2 can be identified as to refer to identical server.In this case, can be used in the information being stored in R2 it is some come more New R1, and R2 (or on the contrary, the information in R1 can be used to modify R2, then can delete R1) can be deleted.At least one In a embodiment, it can be serviced by discovery and realize error correction API, so that client (and/or other authorized entities, it is all Such as the affiliate of professional service analyst, consultant or provider network operator) it can be with regard to such error notification service.Each In kind embodiment, it can be used for broadly improving service operations by the correction that this API is provided, for example, being authorized by one The correction that the given configuration data collection that entity is directed to given services client is made can be summarized and for detecting and correcting pass In the latent fault of the other configurations data set of same client or other clients.

In at least some embodiments, configuration discovery service can be related to different data sources by corresponding trust score Connection, and in which of determine to receive one group of potential conflict or out-of-date profile data element, it can be used such Trust score.Trusting score itself can change over time, for example, if obtaining in service center indicates in client data The dump of the client configuration management database of the heart, then the initial trust score of client database can be set as high level, But over time, score may be decreased, and configuration change can occur at client data center.At least some In embodiment, when generating merging configuration record from original configuration data, it can be used and trust score, for example, trusting number from high It can be wrapped according to the attribute value that source obtains in combined record with the probability bigger than the attribute value obtained from low trust data source Including including.From the attribute value V1 with the data source DS1 for currently trusting score TS1 and from higher current trust point The attribute value V2 of the different data sources DS2 of number TS2 contradict or the situation that conflict in, from the source with higher trust score Attribute value (may include configuring in record in merging, and can exclude from the lower source for trusting score for V2) in this instance Attribute value.In at least some embodiments, machine learning techniques can be used generate and to update over time and change Trust score.

The other details of the various aspects of the operation in relation to configuration discovery service, including set of applications has been provided below The pattern-based automatic grouping of part and label are connect for detecting by obscuring intermediary (obfuscating intermediary) The algorithm in the source of the network packet of receipts, relevance scores are associated with configuration item, for increasing to the responsiveness of inquiry Data model and preloading technology etc..Discuss that Visualization Service and market migrate again after the details for discussing discovery service Service.

In discribed embodiment, each network may include multiple disposition data sources 134, the disposition data source 134 can communicate with configuration discovery service 104.For example, provider network 102A includes disposition data source 134A-134C, it is described to match Data source 134A-134C is set to be collectively responsible for obtaining the configuration data collection of configuration item 136A-136F and be transmitted to service 104. Similarly, provider network 102B includes the data source 134E-134G for being responsible for report configuration item 136H-136L, and customer rs premise Network 172 includes the data source for being responsible for for the configuration data collection for belonging to configuration item 136N and 136P-136S being transferred to service 104 134H and 1341.In some cases, giving disposition data source 134 can be responsible for collecting the configuration number for belonging to multiple configuration items 136 According to, and in other cases, disposition data source 134 can report single configuration item 136.At least for some configuration items 136, configuration Data set can by multiple disposition data sources 134 for example under corresponding granularity level and/or software/hardware stack equivalent layer It collects.In some embodiments, giving disposition data source 134 can be the sub-component of configuration item 136, for example, as in table Show the executive process or thread run at the server of configuration item.For example, data source 134G is shown to configuration item 136L's A part.Some disposition data sources may include the sub-component of existing configuration management tool, for example, in discribed embodiment In, the configuration management database 167 of client includes the data source 134G reported to service 104.

In discribed embodiment, configuration discovery service 104 can realize one or more groups of programming interface 150, wherein Any one may include that for example application programming interface (API), the console based on web, command-line tool and/or figure are used Family interface.The programming interface 150A at curstomer-oriented end can be used for example by client to identify and/or authorize and hold with its application program The associated configuration data of row environment 144 acquires permission, to check the configuration information collected by service 104 (for example, using visual Change service, as further discussed in detail), to obtain in relation to the event of client feedback or the notice of condition may be needed Etc..In discribed embodiment, a group data set is closed and/or service side programming interface 150B can be used for disposition data source Interaction between 134 and service 104, and for by migrating related service 130 and/or using collected service 104 Other services of configuration data construct other feature.

In discribed embodiment, configuration discovery service 104 may include several sub-components, such as the storage of configuration record Library 108, the component 110 for being responsible for the fuzzy original configuration data of merging/elimination and/or responsible appointment/modification data source 134 are corresponding Trust one or more scoring components 112 of score and/or appointment/modification configuration record relevance scores, it is as follows to be begged for By.In at least some embodiments, service may include having different performance ability and/or data model as discussed below Multiple data repositories, for example, configuration record can be pre-loaded in low latency cache from central repository 108 To increase the responsiveness to expected query type.

In discribed embodiment, disposition data source 134 can be sent out to configuration in a variety of formats and at different intervals Now service 104 provides original configuration data set.In some cases, it is connect at service 104 for one or more configuration items 136 The initial data of receipts may be outmoded or out-of-date or inaccurate.In addition, in the original number provided by different data sources 134 Mode according to centralised identity configuration item may be inconsistent in some cases, for example, if given hardware server configuration Have multiple IP address, then can be used by different disposition data sources or by name or position, by other data sources not Server (such as " server 5 of the rack R1 in the computer room 3 of data center DC1 ") is referred to IP address.Described Embodiment in, configuration discovery service 104 can be responsible for merging using multiple technologies, eliminates and obscure and plan original configuration number According to collection.In a kind of such technology, when receiving one group of original configuration data, whether service 104 can attempt data discrimination It is related to known configurations item 136 (previously receive in service center and record the item of configuration data).If new received data are seen Get up and do not correspond to known configuration item, then nomenclature scheme or algorithm can be used to be based at least partially at service 104 One or more attribute values of the ontology of definition and/or the configuration item indicated in initial data, to corresponding to initial data Configuration item generates unique device side identifier.At least in some implementations, unique device side identifier can be with initial data Identifier used in the data source of concentration is different.In fact, service 104 can be responsible for maintaining data in such implementation Mapping between the identifier and unique device side identifier of source report.When service center receives subsequent raw data set, In some embodiments, merging/elimination, which obscures component 110, to map and/or use original configuration data and elder generation using such Before the relevance of data seen identify configuration item applied by raw data set.In some embodiments, be assigned to The service side identifier for determining configuration item 136 can be uniquely in the entire configuration set of records ends being stored at service 104, and In other embodiments, the identifier is in specific configuration domain or NameSpace (for example, domain associated with given client Or NameSpace) can be uniquely.

About analysis and the mode of unique device side identifier is generated in difference using the available configuration data of configuration item Embodiment in can be different.In one embodiment, it can parse first (expansible with XML by different data sources Markup language), JSON (JavaScript object representation), plain text or such as CBOR (concise binary object expression) two The original configuration data that system format provides.Can initial data or normalized number executed in for certain NameSpaces in The associated keyword of uniqueness (such as, for " IPAddr " of Internet protocol address or for intermediate value access control " MACAddr " of location) provide attribute value search, and search result can with Object Type Names (for example, " database take Business device " or " virtualized host ") combination/connection with generate unique device side identifier (for example, " DBServer. < DBVendorName>.<IP address>).In one embodiment, machine learning techniques can be used to improve raw to configuration item At the process of unique device side title.For example, can be used from provider network (for example, identical the mentioning of running configuration discovery service For quotient's network) virtualization calculate the anonymous configuration data collection of large size that the various assemblies of service are collected and be used to generate mark to train The machine learning model of symbol.By the name that the model of earlier version is made determine in it is some may be mistake, for example, identical Configurations item can be endowed two different unique identifiers or two configuration items and can be endowed identical identifier. Over time, when model training is in progress with biggish input data set, error rate can be reduced.

In at least some embodiments, it is corresponding trust score can (for example, by scoring component 112) be assigned to it is corresponding Disposition data source 134, and be used to actually determine which of source of two potentially conflictings given point in time may It is more acurrate.For example, some data sources may include the agency of discovery service 104, the agency can be before the mounting by provider's net The personnel of the operator of network 102B are designed, develop and test, and origin associated with other data sources and/or test level It may not be less known.In latter, higher trust score can be assigned to sometimes and be more familiar with or more preferably manage The data source of solution.In some embodiments, the trust score in data-oriented source can be based on the attribute or life for considering its value Change at the rank of the software/hardware stack of attribute value.For example, data source DS1 and DS2 can respectively provide related preset sequence or The corresponding measurement C1 and C2 that the CPU of process is used.If DS1 collects its cpu busy percentage measurement C1 version at monitor layer, And DS2 is used and is collected its version C2 by the tool that operating system provides, then different trust scores can be assigned to from two The CPU in a source uses attribute value.It, can at least some embodiments that multiple data sources can provide analog value to same alike result The respective weights for indicating current level of trust are assigned to each data source (or { data source, attribute } to), and the weight can For the end value for the attribute that determining discovery service will be used and be saved.In one embodiment, and if worked as from corresponding Data source 134 receives two different raw data sets for corresponding to same configuration item 136, and a raw data set is extremely A few attribute value and the attribute value conflict indicated in another or when contradicting, produce and exclude to have lower trust score The merging configuration of the conflict attribute value of data source is recorded and is stored it in repository 108.In some embodiments, different The trust score of data source 134 can be it is time-weighted, for example, if being collected in time T1 by data source CDSrcl former Beginning configuration data and the initial data that obviously conflicts is collected by another data source CDSrc2 in time T2 (wherein T2 is later than T1), then the initial data collected more recently can be considered more credible.In various embodiments, by merging/elimination The merging data record that fuzzy component 110 generates can be used to provide to by programming interface 150A and/or 150B (for example, coming from Client or other services from provider network 102A) received configuration querying response.

In addition to planning or merging other than the received original configuration data of data source 134, at least some embodiments, It was found that many other functions can be performed in the component of service 104, such as automatic mark corresponds to distributed application program mode together Configuration item group, give the role assignment in such group to corresponding configuration item, the network flow that may have been obscured by intermediary its source Amount implements traffic sources detection algorithm, prepares configuration data actively to support High Performance Data Query etc..Be provided below it is related this A little and other function other details.

As previously mentioned, configuration discovery service can define and utilize the ontology of configuration item at least some embodiments. Fig. 2 shows the example components for finding service ontology that can be used for structuring configuration information according at least some embodiments.? In discribed embodiment, ontology 202 may include multiple object types, and one corresponding with each object type or more The list of a attribute.The analog value of at least some of the attribute of given attribute list of given configuration item may include by various Disposition data source is transferred in the original configuration data set of configuration discovery service.In various embodiments, ontology and original category Property value can be used to configuration item generate unique device side identifier.It, can be by by several attributes for example, in some embodiments Value (some of them can be obtained from different data sources) is connect to construct configuration item with the textual identifier prefix of service creation Unique device side identifier.

For example, object type 204A corresponds to physical host or server.Corresponding attribute list 205A may include CPU class Type, the counting of CPU or core, currently assigned Hostname, monitoring programme (if installation if), operation system information it is various Element (OSdata), one or more IP address etc..The value of given attribute itself in the attribute list of such as 205A may include Several different data elements, for example, " cpu type " attribute may include supplying about instruction set architecture, the CPU supported by CPU The information of quotient, the clock frequency of CPU, model name etc..

Object type 204B indicates process (that is, execution unit at server).The attribute list 205B of process removes other It may include the title of process except item, for corresponding in the order line of calling process, the operating system of host for process Executable file position and/or the path (for example, directory path or folder path) of master catalogue of process, process line Number of passes etc..

Object type 204C indicate network connection (assuming that in this example using transmission control protocol/Internet protocol or TCP/IP race establishes).Attribute list 205C includes source IP address and destination IP address (respectively srcIP and destIP) (example Such as, source, which is identified as to issue connection (), calls to establish the endpoint of connection), originating process identifier and destination Process identifier (respectively srcProcess and destProcess) and/or destination port (destPort).

Object type 204D corresponds to the virtual machine generated using the virtualization frame obtained from particular technology supplier V1. The attribute list 205D of virtual machine includes that the virtual machine identifier (VMID) that defines of supplier, virtual machine are currently running or have run Data center identifier and virtual machine be currently running, plan to run or the host that has run.

In various embodiments, many other object types can be defined in ontology 202.For example, in some embodiment party It, can be for the interconnection device etc. of storage device, the entity of database instance, load balancer/router etc. in case Define corresponding object type.It in one embodiment, can be corresponding right for geographical resource or the grouping definition of other resources As type, for example, the object class that data center can have the object type of their own or server rack that can have their own Type.In some embodiments, ontology can define level or inclusion relation between various objects, for example, many processes can be Run at given host and therefore may include in host, the host process of application program can produce various other processes, these Process can be designated as subprocess of host process etc..In at least some implementations, it can be defined in a manner of object-oriented Relationship between the various entities of ontology.

Merge and the configuration of planning records

Fig. 3, which is shown, merges original match from the corresponding multiple data sources for trusting score according at least some embodiments Example of the confidence breath to generate planning list of attribute values.In discribed embodiment, the number including belonging to given configuration item According to collection 320A, 320B and 320K multiple original configuration data sets 320 by corresponding data source 310 (for example, data source 310A, 310B and 310K) it is transferred to discovery service.Each original configuration data set 320 includes corresponding list of attribute values 325.For giving Fixed host, for example, attribute and its respective value may include " title: host 100 ", " IP address: abcd ", " operating system: < OSVersion > " etc..In at least some embodiments, not all properties value all necessarily corresponds to single configuration item, example Such as, one or more of disposition data source can report multiple configuration items.Different data sets 320 can indicate different particle size fractions Not, for example, a data set may include application-level information (quantity of db transaction that is such as issuing or receiving), and it is another One data set may include lower level details (quantity of network packet that is such as transmitting or receiving).By two different numbers According to source send original configuration data in it is some can correspond to the different time, for example, data set 320A can with number It is collected according to the collection 320K different time.In some cases, belong in the attribute value of given configuration item it is two or more can It can collide with one another, for example, it may be possible to be the case that: a data set instruction has Process identifier at a host H1 The specific process of PID1 be responsible for from different main-machine communications, and another data set can indicate there is another Process identifier The process of PID2 is responsible for such communication.In some embodiments, at least some of disposition data source can opposite discovery service The configuration item for providing data generates corresponding identifier, and includes in data set 320 by these identifiers.This class identifier It can be described as source side identifier, to separate the identifier field of they and discovery service creation.Two data sources sometimes may be used Identical configurations item is referred to using different source side identifiers, for example, a data source can refer to by name Host (for example, " host K. "<domain name>), another can be referred to same host by IP address, and another is referred to by function Generation (for example, " database server DBS1 ").

In discribed embodiment, merging/elimination of configuration discovery service, which obscures component 360, can check and handle institute Have original configuration data set 320, and update (or creation) correspond to its initial data include one in data set 320 or The corresponding merging configuration record 350 of multiple configuration items.In one embodiment, it can be used to merge from two not homologous two The algorithm of a original configuration data set may include at least some of following steps.Firstly, can determine about every in data set One whether include belong to same type configuration item (be such as defined as in the ontology of Fig. 2 202 object type host, Process, virtual machine etc.) attribute value.For this purpose, in some embodiments, it can be by Property Name and the ontology for discovery service In the attribute list (for example, attribute list 205 of Fig. 2) that defines of various configuration items be compared.In some cases, attribute List can indicate identity, for example, passing through by a data source by title AttrName1 and by another data source AttrName2 identifies identical Property Name.If it is determined that two datasets include to belong to same configuration item type at least Some attribute values, then can for relevance, matching or repeatability to these<attributes: value>to checking.For example, if Two datasets all indicate that (a) cpu busy percentage of host during specified time interval is about 75%, (b) and when described Between interim from the host have sent 2500 UDP message packets, then this, which may be interpreted as data set, refers to same host Instruction, even if same host is also such using different source side identifiers.If detecting that such matching (has certain A minimum confidence level), then the single merging record of host creation can be determined as；Otherwise, it is believed that the two data sets refer to Two different hosts of generation, and produce and individually merge record.Merge in record single, from one or two data set Some subset of<attribute: value>of middle taking-up pair is combinable.For example, discardable redundancy/duplicate attribute value, in combined record In may not include certain attribute values because the information that they include can be derived from other included attribute values, or because The more accurate data source of identical data is known.According to the type of data included in data set, in some cases, May be updated it is existing merge configuration record one or more elements or attribute value (or by new attribute be added to it is existing merging match Set record), rather than generate new merging and configure record.

Merge usual can provide of configuration record 350 to provide more than the original possibility of any single original configuration data set 320 The characterization of complete configuration item.Merging configuration record 350 may include the unique device side identifier 352 for configuration item, described Unique device side identifier 352 can be with the corresponding data source that indicates in raw data set 320 in discribed embodiment Identifier is different, and can be based at least partially on the member of ontology and/or original configuration data set that configuration discovery services usually It generates.In at least some embodiments, merge the list of attribute values 354 that configuration record 350 may include planning, the planning List of attribute values 354 may not necessarily include the union for belonging to all properties value list 325 of configuration item.On the contrary, for example, closing And/the discardable certain attribute values from one or more data sources of fuzzy component are eliminated, because these values are outmoded (examples Such as, it because replaced the relatively new value for the same basic attribute that these values have been obtained from other sources, or only because collects Difference between the time of value and the time of processing costs has been more than threshold value).In some embodiments, different data sources is corresponding Trust score 315 (for example, score 315A-315K) may further be used to or alternatively be used to determine given attribute value whether will be included In merging configuration record.When two different data sources provide the initial data for corresponding to same alike result, trusting score can It can be particularly useful: in this case, can be preferential by the attribute value provided with the higher source for trusting score.Each original Data set 320 has in some embodiments for the associated timestamp for indicating when to collect data, timestamp and trust point The formula (in fact, leading to time-weighted trust score) that both numbers are taken into account can be used to select which attribute that should be included in In the list of attribute values 354 of planning.

In some embodiments, and if when the one or more in raw data set 320 gives configuration belonging to item When item is indefinite, then merging/elimination of configuration discovery service is obscured component 360 and can be identified configuration using pattern matching method ?.For example, it is contemplated that such a simple situation: both raw data set 320B and 320K report some configuration item given Approximate outbound network traffic in time interval, and data set 320B include configuration item Hostname and data set 320K Then do not include.In this trifling example scenario, merging/elimination obscures component 360 and can attempt to find included in data set In 320K with the matched attribute value of attribute value in other data sets in similar time periods.If outbound network traffic rate exists It is matched to some threshold accuracy or level of accuracy between data set 320K and 320B, then it can be assumed that the two data sets ( There is no in the case where any contradiction evidence) refer to identical configurations item.

As previously mentioned, in various embodiments, various programming interface can be used in configuration discovery service center.Fig. 4 is shown According at least some embodiments the exemplary application programming interface that service center realizes can be found in configuration.Configuration is shown Data take in four examples (for providing original configuration data set to service) of interface, and show configuration data consumption interface One example of (for obtaining the response to the inquiry for service).

In at least one embodiment, configuration discovery service 460 can provide batch importing/export application programming and connect Bulk information can be for example transmitted to by mouthful (API) 415A, the API 415A from the configuration management database 410 of client Service.In at least some embodiments, service can (for example, passing through downloading) many different agengs 412 are provided, it is described Ageng 412 is mountable at the various physics or virtual bench therefrom to obtain configuration data.Generation can be used in such act on behalf of Reason API 415B comes and communication for service.In various embodiments, at least some of agency 412 collects about particular event Data (for example, every X seconds primary, cpu busy percentage Collection Events can dispatchs at server), and therefore by acting on behalf of The data volume that API 415B is once transmitted may be relatively small compared to by export/importing API 415A transmission data volume.

In some embodiments, configuration discovery services the acceptable original configuration data from various configuration tools 414, Including for example using Simple Network Management Protocol (SNMP), Windows management regulation (WMI) or WBEM, (enterprise based on Web is managed Reason) tool.API 415C specific to tool can be implemented for such tool and configure the interaction between service discovery.? In some embodiments, customization data source 416 that general report API 415D can also be implemented for can developing and dispose (that is, It is not agency itself, data source not associated with third party's configuration tool and not being attached to client configuration management database).

Many different inquiry API 416 can be implemented for the entity of the merging configuration information of consumption discovery service.This Class entity may include other services of provider network, such as Visualization Service and/or one or more migration related service (packets Include migration market service or migration plan service), and configure the client of the provider network of discovery service.Some inquiry API The variant of the 416 available such as well-known query languages of structured query language (SQL).In one embodiment, Time configuration relevant inquiring such as can be used for by the query language towards time series of the OpenTSDB language supported.

Pattern-based grouping and role assignment

Fig. 5 shows can be played the part of in discovery service center using to automatically detect configuration item according at least some embodiments The example of the application architecture mode of the role drilled.In various embodiments, service can support inquiry with search for be used for pair Application program that configuration item is grouped, software and/or hardware configuration mode.In discribed embodiment, configuration discovery The configuration item group descriptor database 590 of service may include multiple group descriptors 510, such as 510A or 510B.Each group of description Symbol 510 may include corresponding MODE name 577 (for example, 577A or 577B), such as " three layers of weblication " or " stage by stage Split and combined application program ", and realize between an application program or the various entities of one group of related application jointly Relationship expression.

Each entity can play the part of specific logical role in programming mode, and can refer in group descriptor 510 Show the expected communication behavior showed by the entity for assigning different role.For example, group descriptor 510A defines four roles: negative Carry balancer (LB) role 511, web server role 512, apps server (Appserver) role 513 and database Server (DBserver) role 514.In the example of one group of configuration item corresponding with descriptor 510A, such as 511A-511C One or more load balancers can pass through one or more web servers of network packet and such as 512A-512N and hand over Mutually.Each web server 512 can also be interacted with one or more application program servers 513 (for example, 513A-513K), and Each apps server then can also be interacted with one of such as 514A-514J or back end database server.It is retouched in group It states in symbol 510B, role can include: be responsible for task splitter 551 that task subdivision is subtask, be responsible for subtasking 1 worker 552 of stage, the result for being responsible for 1 task of collection phase simultaneously divide result to be used for 1 result of stage that the stage 2 is analyzed Combiner 553,2 worker 554 of stage for being responsible for analysis institute's division result and acquisition phase 2 analyze the final result of result Combiner 555.The particular number of configuration item corresponding at least some roles can be different according to the difference of group example.For example, Although individual task splitter, 1 result combiner of stage and most can be instantiated in the configuration item group corresponding to descriptor 510B Terminate fruit combiner entity, but the quantity for being configured as the configuration item of 2 worker of 1 worker of stage or stage can be according to description The difference of the implementation example of symbol and it is different.

In some embodiments, it is found that the client of service can be by programming interface to service commitment descriptor 510 It indicates, and service can identify the corresponding instance for showing the configuration item of the mode indicated in descriptor.Given descriptor 510 can wrap Include the instruction of the various aspects of distributed application program, the expection interconnection topology of configuration item such as associated with application program, With the associated expected item name list (for example, process title or path) of application program and/or associated with application program A pair of of configuration item between expection communication pattern (for example, indicating certain types of request-respondent behavior or initialization/termination The exchange of the data packet of handshake procedure).Service can attempt the behavior and descriptor element phase of the various configuration items for making to observe Match, to determine configuration item just in role.For example, being received in the discribed embodiment of Fig. 5 using from various data sources The configuration data of collection, service may have determined with by merging the unique device side identifier 582A for configuring record 580A and indicating Configuration item by the particular instance of one of the group template of project team ID 586A mark (for example, four layers of weblication Example 1) in play the part of by role of the project team ID 588A indicate role (for example, Web server role).Other configurations item is (such as By merging the item for configuring record 580B and indicating) may not necessarily it play the part of with any to mould-fixed or the associated angle of group descriptor Color；In discribed embodiment, the field role of the project team ID for being used for such configuration item and project team ID can be set as It is empty.In some embodiments, the label for role of the project team ID and project team ID can be used as " label ", play the part of phase to refer to With role or show multiple configuration items of identical behavior pattern.Such label can be used to identify by the client request of discovery service Various operations operand, for example, inquiry " list in data center DC1 with label ' Web server ' all configurations " or order " there is Autonomic Migration Framework of the configuration item of label ' DB server ' to data center DC2 in the DC1 of log-on data center " Logic equivalent can be issued by client.In some embodiments, client can programmatically specify various configuration items Label, then find service such label can be used to identify more modes or group descriptor.In one embodiment, It can be used by discovery service (for example, providing mode/label by the mode and/or label of the client instruction of discovery service Client license under), for role to be grouped and assigned between the configuration item of other clients.

Automatically the network flow source obscured is detected

In many application programs, the networking intermediary of network address translation (NAT) device, port translation device etc. has When can modify network packet in such a way: for configuration data associated with the destination of these data packets Source possibly can not be immediately detected the real source of data-oriented packet.Fig. 6 shows sending out in configuration according at least some embodiments Existing service center uses source identity detection algorithm to network packet.Such source identity detection algorithm is alternatively referred to as source herein Point detection algorithm.As shown, in discribed embodiment, packet collection 622 from flow source endpoint 610 (its It was found that being represented by configuration item in service) flow destination endpoint can be sent to by one or more address obfuscation intermediaries 612 628.Address obfuscation intermediary can also be used in flow in opposite direction (for example, from endpoint 628 to endpoint 610).Destination endpoint It may have one or more disposition data sources associated there, one or more of configuration datas with both source endpoints It is responsible for for configuration data being transferred to discovery service in source.However, due to one or more intermediaries 612 execute obscure operation (for example, Encapsulation etc. in packet header change, enveloping data packet), (it corresponds to the packet collection sent to received data packet collection 623 622) identity of sender may be unclear for the one or more data sources for being attached to destination endpoint 628.From From the perspective of client (it was found that service is in order to which client uses at endpoint 610 and 628), or from obtain belong to one or From the perspective of another service (for example, migration related service) of the configuration information of two endpoints, it is found that the identity of sender can It can be important.

It was found that any one of multiple technologies can be used to identify the transmission square end of received data packet collection 623 in service Point.In at least one embodiment that the respective data sources that can issue order from service are run just at two endpoints, as A part of end-point detection algorithm can be obscured intermediary 612 from endpoint 628 to endpoint 610 by one or more and issue special number According to packet sequence 655.For example, N number of " additional " data packet that interval is exactly T milliseconds (is not one of normal application flow Point) can be issued in sequence of data packet 655 by data source associated with endpoint 628, and including the various other of endpoint 610 Data source at endpoint can actually monitor the input flow rate of the data packet of such precise intervals.Assuming that path between endpoints It is upper without networking bottleneck or problem, the data source at endpoint 610 make received extra data packet interarrival time and end It is possible that the time, which matches, between the transmission of data source at point 628, to establish packet collection 623 with reasonable high probability Sender's identity.In some embodiments, although can IP address at intermediary 612 to various data packets and/or port into Row obscures processing, but can not modify the sequence number of data packet, and can analyze the sequence number of data packet in recipient The source of data packet is identified with end-point detection algorithm with matching at the data source of sender.In one embodiment, may be used Connection dismounting request is issued from endpoint 628 to endpoint 610 and follows the sequence that request is established in connection closely, and such abnormal management is asked Modulus formula can be used to identify source data packet with end-point detection algorithm.In one embodiment, the number run at endpoint 628 It can be issued to the data source (such as another service broker) run at endpoint 610 for unique clothes according to source (such as service broker) The request of business side identifier, and unique device side identifier can be used to identify sender.No matter for detecting sender Specific endpoints detection algorithm how, after sender has been identified, in various embodiments may be updated instruction send The merging of the identity of side configures record.

Relevance scores

Fig. 7 shows can use in configuration discovery service center assigning relevance scores according at least some embodiments To the example factors of configuration item.Relevance scores may be used to determine the initial communication at least to the inquiry for configuration item, example It such as, may include having assigned higher than threshold value to the response for the general inquiry for such as " being listed in the process run on host H1 " The process of relevance scores to reduce the total size of response, and avoids noise or low information response.Although shown in Fig. 7 Particular example sexual factor is suitable for multiple processes, but can also take in various embodiments for other kinds of configuration item Similar method.

Given physics or virtualization calculation server may include hundreds of processes, including many rudimentary or background process, The process, which does not consume many resources usually and is used to (for example, under operating system grade or kernel level), executes background task Or in response to abnormal conditions.Many such processes may be present at all examples of given Edition operating system, for example, In performing environment including 50 Linux servers, one group of similar finger daemon can be run at this all 50 server. At least some consumers for configuring the data of service may be to specific to application program and therefore by default not necessarily The process appeared in the process list of each server is interested.Therefore, configuration service can be different hosts or server The repetition rate 712 of the given frequency at place considers in its relevance scores assignment algorithm 710, wherein (or several in each host Each host) at run those of process assign lower correlation.In discribed embodiment, the resource of process Use the 714, network port using 716 (for example, whether process passes through one or more networks using CPU horizontal, such as recently Port transmission or receive flow) and/or I/O device using 718 can respectively with relevance scores be positively correlated, such as, it is intended to disappear Consuming very low-level resource and/or those of disconnecting process with network can be considered as low correlation.At least one In a little embodiments, the traceable process specifically for given type of configuration discovery service (for example, from given client, Client set or all clients/consumer) inquiry (for example, for entitled " httpd " process inquiry) number Amount.Query history measurement 724 may further be used to determine the correlation of process, for example, if having in past X days by name or angle Color specifically for process inquiry, then high correlation score can be assigned to the process.

In discribed embodiment, it by the relevance scores that algorithm 710 generates can be used to that process is classified or sorted At at least two classifications: having " more interested " process of the score higher than selected threshold value in discribed embodiment 730, and " less interested " process 732 with the score for being less than or equal to threshold value.In discribed embodiment Unless given process relevant inquiring specifies all processes to be included in response, or especially request about being classified as just Otherwise more interested process list can be used to prepare inquiry and ring in the information of the ad hoc inquiry of " less interested " process It answers.In at least some embodiments, similar heuristic can be used to remove or shorten to related other kinds of configuration The response of the inquiry of item.In various embodiments, scoring component 112 shown in Fig. 1 can utilize machine learning techniques next life At relevance scores, trust score etc..

Improve configuration querying performance

It was found that many clients of service can have large-scale application execution environment, it may include and be distributed in multiple data Thousands of configuration items among the heart.Recent variation and/or application component of such client to the configuration of application component Performance or behavior recent trend it is usually interested than old configuration data.Over time, in given application journey The discovery service center of sequence performing environment collects and the total amount of the configuration data of storage may become very large, to potentially slow down Inquiry response, especially to certain traditional data models may be not optimised timeliness inquire.Fig. 8 is shown according at least one A little embodiments can be used in configuration discovery service center to improve the general introduction of the technology for the responsiveness inquired timeliness.

The original configuration data set 871 obtained by data source 802 can be used in the combining block 804 of discovery service, with Generate or update the merging configuration record 872 with timestamp, it is each merge configuration record 872 and configuration item it is one or more only One service side identifier is associated, as previously discussed.In discribed embodiment, merging configuration record 872 can be stored At the partition data repository 820 of the auto zoom of a part for forming one group of persistence discovery service repository 810.One In a implementation, each subregion may include selected the maximum amount of configuration record data (such as M gigabytes), wherein sending out The each client now serviced is initially assigned a subregion.When client configuration data close to client existing subregion When maximum partition size, it can be automatically created for client with associated resources collection (for example, the memory space and/or meter of distribution Calculate capacity) new subregion, and in some implementations, some subsets of client data can be moved to new subregion with into Row load balance.In some embodiments, the database service and/or storage service realized by provider network can be used for holding Long property repository 810.In some embodiments, persistence repository may also include appointing for the query result for being previously generated Select repository 822.Persistence repository 810 can have the average latency L1 for recording retrieval.

In the discribed embodiment of Fig. 8, at least some configuration records can be initiatively pre-loaded to for certain pre- The inquiry of phase type and in the low latency repository 850 that optimizes, as indicated by arrow 875.In various embodiments, remember Record can respectively include creation and/or newest modification time stamp.In at least some embodiments, time sequencing load can be reversed Record, for example, higher priority to be assigned to the record for preloading and updating (or creating more recently) more recently.From repository 850 The average latency L2 of access record is smaller than the waiting time L1 to the record access of repository 810.In at least some realities In existing mode, repository 850 may include being specified for for the volatile memory at the various computing devices of discovery service The part of client query is handled, the inquiry includes looking into mainly for the timeliness inquiry of configuration data recently or time series It askes.In some embodiments, the configuration data cache 852 at repository 850 can be realized inquires specifically for timeliness The data mould of (for example, " logic equivalent for listing the configuration change occurred at server S 1 and S2 in last hour ") Type, data model used in such as OpenTSDB.In at least some embodiments, it can be used for cache 852 most Large space is smaller than available space at persistence record repository, and therefore can abandon older cache as needed Entry 892 is to concede space for newer entry.In at least some embodiments, the result of some inquiries is optionally deposited Storage can be reused as needed at query result repository 822, as indicated by arrow 877.

In some embodiments, the other accumulation layer other than those accumulation layers shown in Fig. 8 can be used, for example, The cold accumulation layer in rear end can be used for having reached the configuration data of threshold value timeliness (such as one month or six months).With main persistence Data storage bank is compared, and such cold accumulation layer (cold storage layer) can have lower cost (and some In the case of using more save space-efficient data format)；However, the waiting time recorded from cold memory scan may be longer.Extremely In few some embodiments, one group of programming interface (or other volume towards the time based on snapshot is can be achieved in configuration discovery service Journey interface), it enables to from the corresponding stamp at fixed time of any different accumulation layer retrieval currently in use or period Configuration record.In one embodiment, the corresponding snapshot of the different time points of client configuration data can be by discovery service certainly Dynamic ground is created and is stored as different objects on demand, this may be implemented at least some time-based configuration queryings Quick response.Snapshot corresponding to various time points can be in various embodiments on demand (or in expected need) from other Layer is loaded into cache 852.In one embodiment, the API based on snapshot may make client to can determine two Whether snapshot configuration is similar enough more useful to make, and if it is then provides this comparison result (conceptually Similar to the result of " difference (diff) " order of configuration snapshot rank).

Method for supporting configuration discovery service

Fig. 9 is to show that the various aspects for finding the operation of service center's execution can be being configured according at least some embodiments Flow chart.As shown in element 901, it may be determined that the one or more application program from client will be started in discovery service center The automatic discovery of the configuration information of performing environment.Performing environment may include at one or more provider networks (for example, in void It is quasi- to calculate service center and/or storage service at the same provider network for realizing discovery service itself and mention at other At quotient's network) and/or client possess or customer account management residency resource.For example, in response to passing through discovery service The request that is received from client of programming interface, it may be determined that start automatic discovery.For example, the service, which can disclose, starts data API is collected, this may cause the automatic discovery of agency's starting of service.For example, agency can be configured to poll API to carry out state Change.When finding the state of service change database to start to collect data, agency can receive this state and update and start to receive Collect data.

It can for example be identified disposition data source initial set (element 904) by discovery service broker, and can be (for example, logical Cross agency) network connection is established between discovery service and data source.Various data sources can be used, it may for example comprise client Existing configuration management database, third party's configuration management and/or performance management tool and/or the customization generated exclusively for client Data source.The programming interface from different classes of data sources original configuration data set can be achieved in service, including export in batches/ Introducting interface, the interface updated for event driven configuration etc..Agency can be configured to transmit data to programming interface.Example Such as, agency is programmed with the information of one or more endpoints of mark programming interface.

Service can start to collect original configuration data set (element 907) from data source.Each data set may include that certain group belongs to Property value and it is some for associated configuration item identification information (for example, pass through data source obtain identifier).Discribed It, can be for example based on being combined with source side identifier, attribute value and/or in the ontology that defines of discovery service center in embodiment The nomenclature scheme of element creates the unique device side identifiers (element 910) of various configuration items.Servicing side identifier can be with number At least some of the identifier provided according to source difference, and can be used to during its life cycle in some embodiments only One ground identifies the configuration item etc. of such as server etc, even if configuration item is physically moved, redeploys for different mesh Be also it is such.In some embodiments, the degree depending on the configuration change applied to specific configuration item, discovery service can Unique device side identifier is modified in passage at any time.Threshold condition for changing service side identifier can be according to configuration item class It is other different and different.In a kind of example scenario, for example, if memory or disk space are added to host, it can Do not change the service side unique identifier of host, but if CPU or motherboard are paged out, unique identifier can be changed.

In discribed embodiment, combinable in discovery service center from various data sources may include about difference The original configuration data set (element 913) of the configuration detail of the same basic entity of granularity, different time or the different tools of use. In some embodiments, raw data set can identify configuration item (for example, can be for corresponding former without using public identifier The same configuration item that beginning configuration data is concentrated provides different source side identifiers), and service and connect using never homologous Relevance or matching between the various attribute values of receipts detect that the configuration data that two different data are concentrated actually refers to Identical configuration item.It produces and merges one or more persistence repositories that configuration records and stores it in discovery service In.

In at least some embodiments, corresponding trust score can be associated from different data sources, and such Trust score can be used to solve the conflict between the configuration data of report, and/or optionally abandon from less credible The received some attribute values (element 916) in source.Therefore, combined planning configuration record can exclude original configuration data set middle finger Some subsets of the attribute value shown.It, can be since oldness be (for example, because certainly in addition to or instead of be excluded due to trusting score The past time is more than the threshold value selected in service center since gathering values) and exclude some attribute values.It can be for example using machine Learning art and/or client feedback carry out the adjustment of passage at any time and trust score itself.
